I think the categorical imperative stops you from harming others, but not from profiting. It is based on free will, after all, so it's not against the individual per se. But to continue your other line of reasoning: there's always someone who profits, and obviously not everybody can profit. There is always a difference. Therefor it cannot be immoral, because it is unavoidable. It is however right to strive for minimal consequences of this difference (in wealth).
